Wolverine Weapon X, Volume 1: Adamantium Men

In the jungles of Colombia, people are turning up dead, whole villages brutally slaughtered by a team of soldiers who move through the shadows like ghosts. On the streets of San Francisco, Logan learns that the files from the old Weapon X program, the blueprints for building Adamantium-laced super soldiers like himself, have fallen into the hands of the evil corporation, Roxxon. Once again, it seems, someone is looking to build the perfect killing machine. That means it's time for Wolverine to step in, and remind them that someone already did. Wolverine: Weapon X (2009) #1-5.
